When you install an OS on top of another OS, and then do the same the following year when the next version comes out, your Mac accumulates lots and lots of files that it doesn’t need. These are added when applications are installed, when they’re run, and when applications like Photos, Safari, and iTunes are used. Over time these junk files can hamper the performance of your Mac. The solution is to give your Mac a cleanup. We recommend CleanMyMac X. It scans your Mac for junk files and recommends to delete them safely.

Before you reinstall macOS Mojave
There are two types of reinstallation. One installs a new copy of macOS Mojave over the current version and leaves everything else intact. The other erases your entire startup disk and installs a clean version of Mojave. The latter is more likely to fix problems and help your Mac run faster, but you’ll have to reinstall all your applications and reconfigure all your settings.
Whichever of the two options you choose, you should back up your Mac first. If you use Time Machine to backup to an external disk or a network drive, you can restore all your applications and settings from that backup after you reinstall macOS Mojave. If you plan to run a clean reinstallation, that’s definitely the simplest route. If you prefer not to use Time Machine, you can use any other backup application, or clone your entire disk.
If you’re reinstalling because you’re going to sell or give away your Mac, you should sign out of iCloud, iTunes, and iMessage first, then run a clean installation.
